pipes'24 pass through the water jacket 16 The end wa'll'of the furnaceis connected 7 to the drum 34.- by a pipe 30; saiddrum 34.-

being connected to a drum 31 by the curved:

pipes 32 which extend vertically within the boiler. The drum 31 isconnected by a Series of pipes with the cylinder or drum 29 which issupported zit-either end by the boiler casing, a drain pipe 35 extendingfrom the drum 29., This drain pipe is provided .with a valve 36 which iscontrolled by-the stem 37, the gear '38 on said ste1nmeshing with a gear39 arranged on the 7 is a e n on the lin -7 f F valve stem 40. Y I v Thegas is admitted through the pipe 11 retaining its heat of gcnerationasit passes .intothe furnace, being supplied as it .en

conles'heated to the high state of ircandes- I cen ce after the furnaceis in operation. As the gases and air properly mixed. pass into thefurnace the mass is ignited by the electric sparkers 4-1.- Itwill benoted that this sparking'of the gases will-be unnecessary after thelining of the furnace has been sufficiently heated, the sparking beingdiscontinned and the gases being ignited by the refract'ory materialwhich is in a state 01 511- candcsccnce. the spark being nit-relyutilized un il the furnace is well heated. The 1 nitcd gases passthrough the tile grille dispo sed adjacent the :end of the furnaceand 1through the pipe 32 to the drum 34i'dis posed withinjthe boiler 17. Thispassingof;:- the gases through the grille and through the pipe 32 "whichconstitutes the cooling co lsfan'd which connects't-he retort 3.4 withthe retort 31 assuring a thorough mixture of the gases and oxygen underthe most favorable conditions conducive to complete rising in'theboiler'1'6.

;pl ete combu'st combustion, the combustion beingpractt,

.The. products of combustion which pa throughthev cooling coils anddesce'n'd the drum 29 pass upward throu h-tliepi 43. The coal tar and.other resi ue passin out;through the drain 35, the. gas fircingij" thetar dshi in' as the valve which is provided with a valve 44'. This?valve 44 consists; of the spherical nozzle 45;"; the topof which isperforated. A valve 465- is arrangeditvithin said nozzle, said valve:

seating itself iu'pfon said valve seat 47 which;

surrounds the 'openingin the nozzle whichi.

the valve 464%31 open and the gases will? pass into the water, passingthrough thesame and qommingling with the steam, the resultant mixturebeing that of a dry permanent gas, saturated with vaporof high specific,and atent heat, this mixture being more valuable in the conversion ofheat enorgy to mechanical, than if the gases were expandedindependently.

Attention iis called, to the peculiar-ar rangem the air or steaminjectonthe I relief valve 19 accurately regulatinm the pressureadmitted to the furnace. 'le

- the structure sli'ownin Fig. l-has been found eflicient, attention iscalled to the. fact :that

various changes may be resorted to and itthe same result secured. '1

In the modified form shown in Fig. 4-, "the furnace is designed: toreceive-oil, convert the same into gas, and ignite the gasthus formed toheat the water in the surrounding jackets. In this form the'furnace isprovided with a suitable oil spray 61,-air

- being admitted in any convenient manner.

Arranged within the mace adjacent the -form a perfect mixture.

this form of the device differs from the precil; inlet is a bafile'wall62, the oilbeing projected against the curved face 63 of said fwa'll,this contact with the WalLIbreaking up the oil and comminglcd steam orair to As before stated frred form only in the fact that the gas isproduced in a different way.
